What are the triggering conditions for the Audi A6L's on-demand all-wheel drive system?
1 Answers
Audi's on-demand all-wheel drive activation conditions are as follows: 1. Snowy conditions: On snowy days, when there is a bit of ice or snow and the front wheels slip, the system activates once the slip is detected. 2. Muddy roads: During heavy rain or muddy conditions where both front and rear wheels slip, the on-demand all-wheel drive starts to engage. 3. Manhole covers: If the vehicle gets stuck in a manhole cover, causing clutch slippage and emitting a noticeable burning smell, the all-wheel drive will also activate. The advantages of on-demand all-wheel drive are as follows: On-demand all-wheel drive simply adds a viscous coupling between the front and rear axles, making its structure relatively simple. This not only effectively reduces costs but also helps lower the overall vehicle weight. It is suitable for models with a front transverse engine and front-wheel-drive platform, enabling many SUVs or all-wheel-drive sedans based on this platform to be equipped with an all-wheel-drive system. The role of on-demand all-wheel drive: It is the most suitable all-wheel-drive system for urban road conditions. When driving normally, the two-wheel-drive mode offers better fuel efficiency. However, in slippery or mild off-road situations, the all-wheel-drive system ensures timely escape.
